INTRODUCTION
The Alamitos Barrier Project (ABP) was designed and constructed to protect the
groundwater supplies of the Central Basin of the County of Los Angeles and the
southwest portion of the Coastal Plain area in Orange County from the intrusion of
seawater through the Alamitos Gap area. The project facilities are located near the Los
Angeles-Orange County border about two miles inland from the terminus of the San
Gabriel River. The original facilities included injection wells to form a freshwater
pressure ridge and extraction wells to form a saltwater trough. The freshwater ridge
that was intended to block the landward gradient of intruding seawater has proven to be
historically effective. However, the saltwater trough that was intended to reverse the
landward gradient of intruding seawater has proven to be historically ineffective. As a
result, the extraction wells are currently not in operation. A map showing the supply
pipeline, injection wells, extraction wells, and observation wells is shown on page A-12.
The County of Los Angeles Department of Public Works (Public Works) operates and
maintains the project and its physical facilities under the direction and approval of the
Joint Management Committee (JMC), acting on behalf of the Los Angeles County Flood
Control District (LACFCD) and the Orange County Water District (OCWD).
This report summarizes design and construction issues, operation and maintenance
activities, hydrogeologic effects, groundwater chloride concentrations, and project costs
for Fiscal Year (FY) 2009-10 (i.e., July 1, 2009 through June 30, 2010).
The JMC is aware that the current depiction of the mergence zones (first implemented
in the FY 2006-07 Annual Report) conflicts with the labeled “Recent Zone Boundary,”
and, though it doesn’t impact data analyses, has determined to resolve this conflict
soon.

SUMMARY
During this reporting period, the total amount of water injected into the ABP was
5,629.2 acre-feet (an average rate of 7.8 cubic feet per second). Of that total, OCWD
purchased 1,320.6 acre-feet (23%) and the Water Replenishment District of Southern
California (WRD) purchased 4,308.6 acre-feet (77%). This total injected amount is less
than in FY08-09, the all-time high, but is consistent with historical volumes and is
slightly greater than the average of the previous five fiscal years (4,851.9 AF). No major
shutdowns have occurred since FY06-07. A timeline detailing the main dates,
durations, and events of those shutdowns is presented in the Injection Operations
Section of both the FY06-07 Annual Report and the July 2007 to December 2007 Semi-
Annual Report. All minor shutdowns for the current reporting period are detailed in
Appendix A-18.
The total cost of the ABP in FY09-10 was $7,169,271 ($7,149,048 for injection-related
operations, maintenance, water, and approved LACFCD and OCWD project expenses;
$20,223 for maintenance of idle extraction wells). Of the total injection-related
expenses, the cost of the injected water was $4,013,439 ($934,993 paid by OCWD and
$3,078,446 paid by WRD) and the total cost of services and supplies for injection and
extraction was $3,155,832 ($699,619 paid by OCWD and $2,456,213 paid by the
LACFCD). The corresponding services and supplies cost to inject one acre-foot of
water was $557.03/acre-foot. This cost, and most of those from FY05-06 and beyond,
is higher than historical amounts because it includes multiple capital improvement
projects. However, it is higher than the previous fiscal year because an abnormally
large volume of water was injected in FY08-09. The project management costs
continue to vary from year to year depending on the need to repair or improve the
barrier facilities. The observation well cleanout costs and injection well redevelopment
costs vary each fiscal year because they are based on cyclical activities.
3
Overall, groundwater levels remained fairly steady in all zones but with localized
increases or decreases due to operational activities. Similarly, chloride concentrations
showed primarily localized increases (some due to existing plumes and others due to
limited operations allowing flow past the barrier), with the exception of fairly widespread
increases in the southeast end of the barrier. Many areas along the barrier and
landward showed decreases in chloride concentrations. Detailed analyses of the
period’s groundwater elevations and chloride concentrations are provided in the
“Hydrogeologic Effects” section and the “Chlorides” section.
PROJECTS AND STUDIES
The current improvement projects and their status are briefly summarized below. The
general location of each project is identified on the map in Appendix A-12 and further
project details are included in the table in Appendix A-17.
Barrier Water Supply Facilities Improvements (BWSFI) Project Phase 2
This project involves bonding the pipe joints and installing sacrificial anodes along the
ABP water supply pipeline. In FY 2006-07, the BWSFI project was split into 2 phases
covering different portions of the ABP water supply line due to certain complications
with right of way and funding. Near the end of FY 2006-07, Phase 1 construction was
completed and Phase 2 Design plans and specifications for Phase 2 were initiated. The
design of Phase 2 continued through FY 2007-08, the project was awarded near the
end of FY 2008-09, and construction began shortly thereafter. The ABP portion of the
project was completed during FY 2009-10 and field acceptance of the overall project is
anticipated in early FY 2010-11.
ABP Condition Assessment
This project is jointly funded by the LACFCD, OCWD, and WRD, but is being managed
by LACFCD. It involves the evaluation of portions of the ABP water supply pipeline,
along with selected injection wells, observation wells, and extraction wells. The scope
4
of work and cost-sharing agreement were developed during FY 2008-09. The project
was advertised, awarded, and initiated during this reporting period. Work is expected to
be completed late in FY 2010-11.
ABP Groundwater Model
This project is jointly funded by the LACFCD, OCWD, and WRD, but is being led by
OCWD. It involves the development of a groundwater model that will be used to
operate the ABP more efficiently, identify locations and scenarios where new wells
could make the ABP more effective against seawater intrusion, and to predict the flow
and transport of injected reclaimed water. The scope of work and cost-sharing
agreement were developed and finalized during FY 2008-09. The project was
advertised, awarded, and initiated during this reporting period. Work is expected to be
completed early in FY 2010-11.
ABP, DGBP, and WCBBP Injection Well Condition Assessment
This project involves the evaluation of injection wells at all three seawater barriers. For
the ABP, it includes all the injection wells not assessed during the ABP Condition
Assessment. The project was advertised and awarded during this reporting period, and
work is anticipated to begin early in FY 2010-11.
New Observation Wells in Orange County
The OCWD completed the construction of 8 new observation well casings in late 2009.
Well 34X40 was constructed in an area where there were no other observation wells in
the vicinity in order to fill in data gaps. Additional casings were added at existing wells
sites 35J1 and 35K1 in order to monitor additional aquifers (i.e., I zone and C Zone).
Well 35K’12 was constructed as a replacement for 35N’15, which was destroyed during
the Orange County Flood Control District’s construction of the Los Alamitos Retarding
Basin. A summary table of the well construction details is included in the Appendix
(A-19). All applicable documentation has been filed with both LACFCD and OCWD and
the wells have been incorporated into LACFCD’s monitoring schedules.

Destruction of Observation Well in Los Angeles County
The LACFCD completed the destruction of observation well 34H’38 in July 2009 after
an attempt to bring the well up to standards by installing a surface seal was
unsuccesful. All applicable documentation has been filed with both LACFCD and
OCWD and the well has been removed from LACFCD’s monitoring schedules.
INJECTION OPERATIONS The total amount of water injected into the ABP during this reporting period was 5,629.2
acre-feet. Of this total, 41% (2,300.6 acre-feet) was reclaimed water and 59% (3,328.6
acre-feet) was imported water. The percentage of reclaimed injection was the highest
it’s ever been, primarily because the reclamation plant was in operation fairly steadily
during this entire reporting period. There were still a number of interruption in reclaimed
water delivery, but most were very brief. There were only a few periods longer than one
week where the reclamation plant was out of operation due to maintenance activities on
the reclamation plant or the barrier itself.
According to the California Regional Water Quality Control Board (CRWQCB) permit,
File No. 93-076 of Order No. R4-2005-0061, the 60-month running average of reclaimed
water into the ABP cannot exceed 50 percent. Since ABP reclaimed injections began in
October 2005, the 60-month period includes injections prior to the delivery of reclaimed
water into the barrier. Through this reporting period, WRD’s calculated 60-month
running percentage of reclaimed water into the barrier is 27.5% and is therefore in
compliance. Public Works’ calculation through this period (which is consistent with the
volumes identified throughout this report) is 28.0%. The slight discrepancy is due to
differences in the timing and calculation methods of the monthly meter readings for both
imported and recycled deliveries prior to April 2008.
The maximum monthly injection for this reporting period was 563.9 acre-feet (288.0
acre-feet imported and 275.9 acre-feet reclaimed) and occurred in January 2010. The
6
minimum monthly injection of 302.7 acre-feet (169.5 acre-feet imported and 133.2 acre-
feet reclaimed) occurred in July 2009 since the barrier was off for the repair of a leaking
section of supply pipeline just upstream of the pressure regulating valve.
The injection volumes and costs from July through June of both FY 2008-09 and FY
2009-10 are shown in Table 1. The representative reclaimed unit costs included in
Table 1 are calculated by WRD and a complete historical record of these unit costs is
available from any of the agencies comprising the JMC. Table 1 shows a decrease in
total injection amount from FY 2008-09 to FY 2009-10. This decrease was the result of
resuming more normal operations following the abnormally high amount in FY 2008-09.
That large amount in FY 2008-09 was possible only through gradual increases in
operations to meet the temporarily higher demand at the barrier caused by the multiple
previous shut downs throughout FY 2006-07.
The ABP operational status for FY 2009-10 is summarized in Appendix A-18 and there
were no major shutdowns requiring further discussion in the body of this report.

EXTRACTION OPERATIONS
There were no extraction activities during FY 2009-10. As recommended by the JMC
Committee, these wells were taken out of operation in FY 2002-03. This decision was
based on results of the one-year extraction well efficiency study, which demonstrated
that the chloride levels in the area decreased when the extraction wells were turned off.
The extraction wells will continue to receive minimal maintenance so that they can be
turned back on if deemed necessary in the future. Since there has been no extraction
activity since FY 2002-03, the traditional summary tables are no longer included in the
annual reports.
MAINTENANCE Typical well maintenance at the ABP includes observation well cleanouts and injection
well redevelopments. The purpose of observation well cleanouts is to remove
accumulated sediment at the bottom of the well casings. Removing the sediment
ensures the full lengths of the well screens are in communication with the aquifer, and
also allows chloride sampling to occur at all designated depths. The occurrence of
sediment accumulation within the observation wells is typically analyzed every two
years for all 221 active observation wells. Following the analysis, all observation wells
determined to have significant sediment accumulation (i.e., covering a portion of the
well screen) then receive the necessary cleanout services. Once cleanout activities are
completed, the logs for each casing are typically analyzed to determine whether or not
sediments were removed successfully and any resulting recommendations. During this
FY09-10 reporting period, there were no ABP observation well casings cleaned out. A
new cleanout cycle will occur following the completion of the current redevelopment
cycle, which estimated to end in February 2011.
10
The purpose of injection well redevelopments is to remove accumulated sediments and
microbiological build-up within the well casings to restore each well’s ability to operate
at its maximum injection capacity. Each of the 45 injection and extraction well casings
are routinely developed once every two years. During FY 2009-10, Public Works
completed the redevelopment of the following 27 injection well casings1: 35G(A,I),
34Z(I), 34V(C,B), 34V(A), 34V(I), 34S(I), 34S(C,B), 34S(A), 34H(A), 34H(I), 34F(I),
34F(A), 34E(I), 34E(C,B), 35H2(A), 35H1(A), 35H1(I), 34G2(C,B), 34G2(I),
34L(C,B,A,I), 34J(A&I), 34G(A), 33Z(C,B,A,I), 33Y(C,B,A,I), 33X(C,B,A,I), 33Z2(A,I),
and 33W(C,B,A,I). One casing was completed at the end of the previous Fiscal Year,
so there are 17 more casings still to be redeveloped as part of this current “two-year”
ABP redevelopment cycle that started in June 2009.
Figure 3 depicts the operating status of each injection and extraction well during
FY2009-10 and demonstrates that the barrier has predominantly been in operation
throughout this reporting period. Nonetheless, there were a few instances of
nonoperation due to aquifer pressure limitations (33Q and 35H1), surface leakage
(33S1 and 34G), well redevelopments (various), and repairs (various). As indicated,
there were also other periods of localized nonoperation and two brief periods of full
barrier nonoperation due to “Other Circumstances” which are explained in Appendix
A-18. The transition time before and after all periods of nonoperation will continue to be
minimized as much as possible.
1 The capital letters in parenthesis represent the aquifer(s) receiving injections from that well casing. For example, (A) = A Zone aquifer, (A,I) = A and I Zone aquifers, and so forth.

HYDROGEOLOGIC EFFECTS
Figures 4 through 8 (pp. 13-17) show the average monthly groundwater elevation
against the 10-year average groundwater elevation (of the 10 preceding years) in the
vicinity of the barrier alignment in the R, C, B, A, and I Zones, respectively. Two graphs
were created for each aquifer to account for changes in groundwater elevation trends
along the barrier alignment: wells west of the San Gabriel River and wells east of the
San Gabriel River. It is important to note that the 10-year average does not represent
an injection goal but is simply included for the sake of comparison. For example, the
running 10-year average in this report is typically slightly lower than that shown in the
FY08-09 report because the FY08-09 data now included was actually slightly lower than
the FY98-99 data it replaced. The data includes all available semi-monthly, monthly,
semi-annual, and annual values for wells within the barrier alignment and landward for
approximately 2,000 feet from the barrier. As a result, the semi-monthly values are
“weighted” more heavily than the annuals in the calculation of the monthly average. In
each figure, monthly average groundwater elevations during FY 2009-10 are compared
with the averages of the previous 10 years (Fiscal Years 1999-00 to 2008-09).

Since groundwater elevations have remained below average throughout the Central
Basin, it is no surprise that the same is true in the area immediately surrounding the
ABP. As shown, groundwater elevations were only at or above historical averages a
few times during this entire reporting period, primarily in the fall months of 2009. These
ABP groundwater elevations have typically been below historical averages in recent
fiscal years as well, despite the barrier being back in operation following the FY06-07
shutdowns. This is likely due to significantly increased pumping from both the Central
and Orange County groundwater basins (both basin-wide as well as local to the barrier)
and reduced natural recharge in the Orange County groundwater basin.
It is noted that, in general, all the figures show the expected seasonal groundwater
elevation trend of higher elevations in the winter months (decreased pumping) and
lower elevations in the summer months (increased pumping). However, the seasonally
low groundwater elevations in July 2009 and May 2010 were further exacerbated by
barrier shutdowns. The other lower-than-expected elevation occurred in December
2009, but can also be attributed to one of the barrier shutdowns (identified in A-18).
The full barrier shutdowns in July 2009 and December 2009 were to temporarily and
then permanently repair a portion of the water supply pipeline upstream of the PRV.
The east-leg shutdown in May 2010 was to repair a portion of the supply pipeline
damaged by the Los Angeles Department of Water And Power.
Groundwater elevation contours for the R, C, B, A, and I Zones have been prepared
from data collected in March 2010 and are included in Appendix A-1.1, 2.1, 3.1, 4.1, and
5.1. A list of all data points used for these contours is also included in the Appendix (A-
1.3, 2.3, 3.3, 4.3, and 5.3). As expected, the contours show that the groundwater levels
typically decrease as you move landward of the barrier. The general shapes of each
contour are similar to the previous year and the effects of the barrier are demonstrated
in the various groundwater mounds seen around some of the injection wells. Also, it
should be noted that areas historically having higher groundwater elevation contours,
especially near the bend at the San Gabriel River, continue to have higher groundwater
19
elevations than their surroundings. Some of these historically higher areas (e.g., near
33XY and 33YZ) are also believed to be more sensitive to shutdowns because the
influencing injection wells (e.g., 33X, 33Y, and 33Z) inject into all four zones from one
casing and therefore require larger volumes of water to maintain protective elevations at
all four corresponding observation wells. These same observation wells demonstrate
the most significant changes in elevation from barrier startups and shutdowns and are
the largest contributors to the low and high points seen in Figures 4 through 8.
Also, this FY09-10 report is the first to include additional groundwater elevation contours
for the R, C, B, A, and I Zones that plot the change in elevation between March 2009
and March 2010 (A-1.2, 2.2, 3.2, 4.2, and 5.2). The data set is based on available data
from March 2010, which was then subtracted from the corresponding and available data
from March 2009 (shown in A-1.3, 2.3, 3.3, 4.3, and 5.3). These contours very clearly
identify the increases and decreases in elevations from one reporting period to the next,
and serve to replace the previous “Groundwater Elevation Summary” (Table 2 in past
JMC reports). A brief summary and discussion is as follows:
• R Zone:
o Two foot decreases in the northwest with a gradual gradient to 2-foot
increases in the southeast.
• C Zone:
o Localized 6 to 8-foot decreases around 33XYand 33YZ (because 33Z was
off for redevelopment immediately preceding the data collection and 33Y
was off for redevelopment at the time of data collection).
o Localized 2-foot decreases around 34L’1 to 34T0.1 (likely due to reduced
injection due to 34L’s inoperation at the time of data collection).
• B Zone:
o Localized 6 to 8-foot decreases around 33XYand 33YZ (because 33Z was
off for redevelopment immediately preceding the data collection and 33Y
was off for redevelopment at the time of data collection).
20
o Concentrated 4-foot decrease around 34T0.1 (likely due to the inoperation
of 34V during well reconstruction prior to the time of data collection).
o Increases of up to 2 feet in the northwest and 2 feet in the southeast.
• A Zone:
o Localized 4 to 6-foot decreases along the center of the barrier alignment
(because preceding or during the data collection, multiple wells in the area
were periodically off for redevelopment, 34G was off for surface leakage,
and 34L was off for tremie repairs).
o Localized 2-foot increases on west and southeast ends of the barrier.
• I Zone:
o Localized decreases of about 4 feet around 33XYand 33YZ (because 33Z
was off for redevelopment immediately preceding the data collection and
33Y was off for redevelopment at the time of data collection).
o Decreases of about 2 feet to 12 feet along the east leg of the barrier and
centered around 34T0.1 (partly because preceding or during the data
collection, 34L was off for tremie repairs, 34V was off for well
reconstruction, and a couple wells were redeveloped).
o Increases of up to 12 feet northwest of the barrier.
For further analyses of the C, B, A, and I Zone groundwater elevations, please refer to
the graphs included as Appendix A-13 through A-16. These graphs show the average,
maximum, and minimum groundwater elevations at each internodal observation well
throughout FY09-10 in relation to the ground surface and the protective elevation.
These graphs were implemented for the FY07-08 report as requested at the
corresponding JMC technical meeting and have replaced the previous graphs that
showed the elevations of individual wells over the given reporting period. As shown in
A-13 to A-16, the average groundwater elevation was below the protective elevation at
many wells along the barrier during FY09-10. However, elevations below the protective
elevation did not necessarily correlate with areas of high chloride concentrations. A
comparison of these graphs to the previous year’s graphs indicates that overall
21
elevations generally remained fairly steady, but, similar to what was seen in the
contours, there were a number of localized increases or decreases due to various
operational activities. In all cases, the southeast portion of the barrier remained below
protective elevations due to the limited injection capabilities (quantity of wells, pressure
limitations, maintenance, etc). It is important to note that the JMC is seeking to
remediate the limited injection capabilities in the southeast region through potential
additional wells, modeling studies, grouting operations, and condition assessments to
allow preventative maintenance.
CHLORIDES
Figures 9 through 13 (pp. 22 – 26) show the historical chloride concentrations (the
average of the maximum value throughout the year for each observation well) in the
individual aquifer zones. The data includes all available information from the annual
and semi-annual sampling events for wells within the barrier alignment and landward for
approximately 2,000 feet from the barrier. As a result, the semi-annual values are
“weighted” more heavily than the annuals in the calculation of the annual average. Two
sets of graphs were created for each aquifer to account for changes in chloride
concentration trends in the areas to the west and east of the San Gabriel River,
respectively. In each figure, the average of the annual maximum chloride
concentrations for the last 10 fiscal years (including this year) is shown with respect to
the freshwater condition (250 mg/L).

As shown, Recent Zone chloride concentrations decreased in both regions. East of the
San Gabriel River, FY09-10 chloride concentrations increased in every zone receiving
injection water, though in the C Zone values stayed “fresh” and in the B Zone it was a
small increase. The larger increases in the A and I Zones are primarily due to drastic
increases at only one or two wells in the southeast portion of the barrier (35H11 for the
A Zone; 35E0.1, 35F20, and 35H11 for the I Zone), likely due to limited injections.
West of the San Gabriel River, FY09-10 chloride concentrations in the A and I Zones
decreased and were at or below 250mg/L. However, westerly chloride concentrations
in the C and B Zones showed significant increases, mainly because of very high values
at 33ST that are the potential result of the barrier shutdown in July 2009. However, this
well was sampled 3 times during this reporting period and decreased substantially each
time (about 11,000mg/L decrease overall). The decreasing trend at this well is
expected to continue.
Chloride concentration contour maps for the R, C, B, A, and I Zones have been
prepared from data collected in the Spring of 2010 and are included in Appendix A-6.1,
A-7.1, A-8.1, A-9.1, and A-10.1, respectively. A list of all data points used for these
contours is also included in the Appendix (A-6.3, A-7.3, A-8.3, A-9.3, and A-10.3). The
chloride contour maps are based on the maximum chloride ion concentration (mg/L)
measured at each observation well. Chloride data was gathered from observation wells
located within the immediate vicinity of the barrier and does not represent basin-wide
conditions for the groundwater basin protected by the barrier. Wells with chloride
concentrations of 250 mg/L or less were considered fresh. The chloride measurements
used in this report were from the semi-annual sampling event in March 2010 and the
annual event in the February and March 2010. In a few instances, it was necessary to
incorporate data from previous reporting periods (provided it was historically consistent
and reasonable) in order to create the most accurate and complete representation of
the conditions around the barrier.
28
Also, this FY09-10 report is the first to include additional chloride concentration contours
for the R, C, B, A, and I Zones that plot the change in chloride concentration between
Spring 2009 and Spring 2010 (A-6.2, A-7.2, A-8.2, A-9.2, and A-10.2). The data set is
based on available data for Spring 2010, which was then subtracted from the
corresponding and available data for Spring 2009 (shown in A-6.3, A-7.3, A-8.3, A-9.3,
and A-10.3). These contours very clearly identify the increases and decreases in
chloride concentrations between these two reporting periods, and serve to replace the
previous “Chloride Concentration Summary” (Table 3 in past JMC reports).
The chloride concentration contours and chloride concentration cross-section (A-11) for
this reporting period indicate that intrusion of seawater across the barrier continued to
be controlled along much of the alignment. However, several areas recorded elevated
chloride concentrations. For all zones receiving injection water, the southeastern end of
the barrier continued to show elevated and increasing chloride concentrations at most
wells. Additional areas of high chloride concentrations and/or notable changes in
concentration (since the FY08-09 report) are as follows:
• R Zone – High chloride concentrations were present north of west leg along Los
Cerritos Channel and around 34L’1 on the east leg. Notable decreases and
increases occurred as shown but are independent of injection operations.
• C Zone – High chloride concentrations were found near the west leg along Los
Cerritos Channel. Increases in chloride concentrations occurred around the Los
Cerritos Channel and seaward, but there were generally minimal changes or
decreases landward of the barrier
• B Zone – West of the Los Cerritos Channel, there were high (and increased)
chloride concentrations. The increases at the southeast end of the barrier are
most significant at 34U8.
• A Zone – High chloride concentrations remain northwest of the west leg and
certain wells therein have increased. A small increase occurred at 33UV, but
the majority of the barrier alignment and landward showed minimal changes or
29
decreases in chloride concentrations, especially where the barrier intersects the
San Gabriel River.
• I Zone – Chloride concentrations decreased in general along the west leg and
northward. There were increases on the east leg at well 34LS.
There are three possible causes of the high chloride concentrations north of, northwest
of, and along portions of the ABP west leg (which was predominantly in steady
operation during this reporting period). These include the transportation of seawater
inland by the Los Cerritos Channel, a need for greater protection to prevent wrap-
around on that end of the barrier, and remaining seawater from previous intrusions. It is
likely that an increase in chloride concentrations at other locations is still a continued
result of the extended barrier shutdowns in 2006 and 2007. The drastic increase in
concentration at 34LS(I) is likely the result of the inoperation of 34L in the spring months
of 2010, which has since been remedied. Further, the chloride concentration decreased
at 34LS with each subsequent measurement throughout the reporting period (with a
total decrease of about 6,500mg/L) and is expected to further decrease quickly due to
the continued maximization of operations at 34L and 34S. The increases around much
of the southeast end of the barrier are likely caused by the limitations of the existing
injection wells.
It is important to note that the new OCWD observation wells provided additional data
within Orange County but are not used in the “change in concentration” contours since
no previous data was available. LACFCD is also planning additional observation wells
which will aid in further understanding the conditions within LA County, particularly north
and west of the west leg. Ultimately, both LACFCD and OCWD plan to utilize the
additional data to determine whether or not to construct additional injections wells as
necessary to better prevent seawater intrusion.
As discussed before, the extended shutdowns in FY06-07 and the resulting increases in
chloride concentrations demonstrated that the barrier is effective when in operation. As
expected, there were therefore many decreases in chloride concentrations in the FY07-
30
08 reporting period where the barrier resumed more normalized operation. In FY08-09,
there were multiple increases in concentration inland of the barrier in all zones except
the I Zone even though most internodal locations decreased, perhaps due to the
continued injection pushing small plumes of intrusion that arose during the prior
shutdowns. In FY09-10, there are indicators of the same small plumes moving further
inland but the barrier is effectively preventing new intrusion while in operation (34LS and
the southeast end of the barrier continue to show the impacts of limited operations).
It is imperative that the barrier operate consistently and continuously to best prevent
seawater intrusion. The JMC has discussed ways to minimize barrier down time and is
currently performing the condition assessment project of the entire facility that will allow
proactive maintenance rather than reactive. Additionally, the JMC will be ready to
pursue the fastest option for as-needed/emergency contract repair work. The JMC and
Public Works will continue to press forward to ensure that the ABP is most efficiently,
economically, and continuously protecting the region’s groundwater supplies.

FINANCING AND COSTS
This section of the report is divided into four parts: Water Costs, Services and Supplies
Costs (operation and maintenance), Fixed Assets Costs (capital outlay), and Budget.
Under the terms of the 1964 Cooperative Agreement between LACFCD and OCWD,
fixed assets are typically divided into facilities paid for by the LACFCD, facilities paid for
by the OCWD, and joint facilities paid for by both agencies, depending on their location.
Under the same agreement, water costs are divided between the LACFCD (whose
portion is paid by the WRD per a separate agreement) and the OCWD. The total cost
of the ABP in FY09-10 was $7,169,271 ($7,149,048 for injection-related operations,
maintenance, water, and approved LACFCD and OCWD project expenses; $20,223 for
maintenance of idle extraction wells).
WATER COSTS During the 2009-10 fiscal year, 5,629.2 acre-feet of water were injected at a total cost
of $4,013,439. The monthly water rates (dollars per AF) from July 2009 to June 2010
varied periodically as shown earlier in Table 1. The monthly quantity of water injected
and the total water costs paid by each respective agency are shown below in Table 2.

SERVICES AND SUPPLIES COSTS As shown in Appendix A-20, LACFCD spent a total of $3,155,832 on services and
supplies during the 2009-10 fiscal year (excluding liability insurance and water costs).
Pursuant to the 1964 Cooperative Agreement, the OCWD pays a percentage of the
services and supplies costs for injection operations proportional to the percentage of the
total amount of injection water paid for by the District. As a result, for this fiscal year,
LACFCD was responsible for 79% of the $3,043,151 for injection services and supplies
while OCWD was responsible for the remaining 23%. The distribution of FY 2009-10
services and supplies costs is summarized in Table 3.

1 The higher costs per Ac-Ft injected in FY05-06 and beyond are typically because these years included
costs for multiple repairs and/or capital improvement projects whereas not all other years did. The cost is
especially high in FY06-07 because the improvement projects, observation well cleanouts, costs related
to the reclaimed water program, and various fixed costs were still incurred despite reduced injections due
to the extended shutdowns for repairs.

The costs of the services and supplies for extraction operations for the last 20 years,
including electrical costs, are shown in Table 5.

The increase in cost for the last two fiscal years is due to increased maintenance needs
at two of the deteriorating extraction well sites, 33V’15P and 34H’17P.
FIXED ASSETS During Fiscal Year 2009-10, there were no new LACFCD facilities or joint facilities
added to the ABP. However, new OCWD facilities consisted of 8 observation wells
casings as discussed earlier in the “Projects and Studies” section.
35
Public Works spent $1,319,623 on multiple capital improvement projects (including
contracts and labor), primarily on the groundwater model, the wells and facilities
condition assessment, and the implementation of cathodic protection along the supply
line. However, small amounts were also spent on the new injection well assessment
project, as well as some minimal wrap-up costs for the telemetry system phase 2 and
the ABP pressure reducing valve renovation. As agreed at the previous annual JMC
meetings, these capital improvement costs (minus the groundwater model and condition
assessment contract expenses dealt with per separate agreements) were incorporated
into the operation and maintenance costs (i.e., services and supplies) so that OCWD
covered a portion of these costs in accordance with the distribution of water delivered
(23%). Also, OCWD contributed an additional $130,815 (shown in Appendix A-21) to
cover their remaining balance due on the cathodic protection projects contract costs
because it had been previously agreed that OCWD would cover 32% (based on the 5-
year FY00-01 to FY04-05 water distribution average) of the total cathodic protection
contract costs and yet has only been paying annually per the respective distribution of
water delivered (which have been lower than 32%). Therefore, in FY09-10, OCWD was
responsible for $424,144 (32%) of LACFCD’s $1,319,623 expenses on capital
improvement projects (see Appendix A-20).
The actual contract costs for the groundwater model and the condition assessment
projects have been, and will continue to be, divided according to the cost-sharing
agreements between LACFCD, OCWD, and WRD.
BUDGET The FY2011-12 budget for the ABP is $1,835,200. A breakdown of this amount, along
with past expenditures per category, is shown in Appendix A-22. Note that amounts for
WRD are shown in addition to those for LACFCD and OCWD.

NOTE: For O&M purposes, LACDPW prefers future new observation wells be 4-inches in diameter. The larger casing size allows more samples to be obtained at one time and typically does not get obstructed or skewed as often as narrower wells.

Plus: Remaining Balance Due to Complete OCWD Share of Cathodic Protect 130,815.00$
BALANCE DUE FROM ORANGE COUNTY WATER DISTRICT 429,979.56$
1 OCWD share represents 23% of the total costs in all Items except for 4, 5, 6, 10, and 13. The percentage is based on amount of overall barrier injection water provided to Orange County portion of the ABP during this fiscal year.2 Per Agreement No. 8458 between the LACFCD and the OCWD, all costs included in Items 4, 5, 6 and 13 are not reimburseable with respect to OCWD and the OCWD cost for Item 10 is fixed at $375.00.
(Reimbursable amounts include labor expenses, plus contract expenses that are not addressed under a separate agreement [such as the model and Condition Assess]).
* THIS NEW FORMAT ACCOUNTS FOR CAPITAL IMPROVEMENT PROJECTS AS THEIR OWN CATEGORY AND
ALSO ACCOUNTS FOR SPLITTING UP LABOR EXPENSES FROM CONTRACT EXPENSES FOR APPLICABLE PROJECTS (WHERE SEPARATE COST-SHARING AGREEMENTS ARE IN
PLACE FOR CONTRACT AMOUNTS)
= OCWD's portion of our $1,319,623.38 projects cost (after adding in final Cathodic Protection contribution)
= LAC's total expenses on CI projects (1,250,345.50 + 69,277.88)

NOTE: This FY11-12 budget is the first to include the addition of Category 15 (Projects and Studies). All items within Category 15 were previously included in other categories. Starting with FY09-10, budgeted and actual amounts have been redistributed accordingly (but do not impact previous totals). As a result, past amounts shown hereon may not match what is shown on past budget sheets, but reflect the more detailed breakdown of effective costs/budgets. Project-related labor costs and contract costs not governed by separate agreements (i.e., Cathodic Protection) are addressed in Category 15. Contract costs governed by separate agreements are addressed as part of Category 13.
